SSLProtocolException "No access possible to the CalDAV or CardDAV service"



First, sorry for the translation, I m belgian so the translation may not be exact ...

There is the debug.txt that i've got when trying to connect to a nextcloud server with davdroid from a Huawei P7lite. The message popping is the title of the topic.

Can someone tell me what's the problem, and how can I solve it ?

Thank's a lot,
